Trademark abandonment doesn't equal total forfeit, as MS also abondoned the trademark for Blinx, yet still made it BC on XBO, which I'm assuming they did as they still own it.
Meaning, they own the IP, this is just means they're not as caring of it I guess. The Wonderful 101 is probably the only time in the last near 20 years Nintendo ever surrendered an IP, with Rare's catalogue being the only ones prior to my knowledge, and there was a rumor that Iwata tried to retain ownership but the board of directors overruled him apparently. Don't remember where this was said but it's all I remember of the story.
